THUMB FRACTURES

If you suffer from severe pain due to hand or wrist injury, please Schedule an appointment with one of our orthopedic specialists as soon as possible.

What is a thumb fracture?

Due to its solitary position on the hand, the thumb is highly prone to fracture. It comprises two phalangeal bones and a metacarpal bone, any of which can sustain injury. Additionally, the trapezium, the wrist bone on which the thumb rests, may also be affected. A prevalent fracture involving the base of the thumb metacarpal bone and the joint is known as the Bennett fracture. Another type of fracture, the Rolando fracture, is more complex, extending from the base of the thumb metacarpal bone and further involving the joint.

What causes thumb fractures?

A thumb fracture may result from falling on an outstretched hand, sustaining a sports injury while catching a ball, or being involved in an accident. Typically, the fracture occurs due to impact on a partially flexed thumb.

What are the symptoms of a thumb fracture?

You may suspect a thumb fracture if you experience pain, swelling, noticeable bending, or difficulty moving your thumb after an injury.

Diagnosis and Treatment

Diagnosis

Diagnosing a thumb fracture involves conducting a clinical examination and reviewing imaging results. Typically, X-rays with specialized views of the thumb are adequate for diagnosis. However, in some cases, physicins may deem a CT scan necessary to provide further details about the injury.

Treatment

The treatment for a thumb fracture depends on factors such as the location and extent of the injury, as well as whether additional structures like ligaments are involved. Additionally, immobilization with a cast or splint may be part of the treatment for several weeks. Surgical intervention might be necessary for severe fractures, involving stabilization with surgical wires like Kirshner or K-wires. In cases requiring further fixation, surgeons may perform surgical reduction and fixation with screws or small plates through an incision. Hand therapy may be necessary during recovery to assist in regaining strength and range of motion in the thumb.
